A laminated coating film () includes a metallic base layer () and a color clear layer, and produces a target color with the metallic base layerand the color clear layer (). The laminated coating film () is designed to have high chroma at the highlight, and further to provide an appearance of denseness. To address this, the laminated coating film satisfies the following formula (1):()&#x3e;60&#x2003;&#x2003;(1)where Rrepresents a highlight reflectance of light of the target color, and Rrepresents an average highlight reflectance of light in a wavelength range outside a hue range of the target color.

Laminated coating film and coated article

One aspect of the present invention is a laminated coating film structure having a laminated coating film that renders a specific color on a coated object, wherein the laminated coating film is provided with a first layer arranged on the side close to the coated object and containing a pigment in which the mean particle diameter is &#xbd; or more the wavelength of the specific color but 2 um or less, and a second layer arranged on the side far from the coated object and containing a pigment in which the mean particle diameter is 0.05 um or more but less than &#xbd; the wavelength of the specific color.

The purpose of the present invention is to obtain a method for forming an excellent multi-layer coating film of high chroma and brightness and a rich color. With the method, color mottling does not occur easily in the coating film and the design obtained is homogeneous even without strict control of variations in film thickness during coating. The method for forming the excellent multi-layer coating film comprises: forming a metallic base coating film on the surface of the object to be coated by applying a metallic base coating containing a shiny material; then forming a color base coating film by applying a color base coating; subsequently forming a clear coating film by applying a clear coating on the color base coating film; and heat-curing the metallic base coating film, the color base coating film and the clear coating film obtained. In the method, the light reflectance of the metallic base coating film is in a specified range and the light transmittance of the single color base coating film obtained by heat-curing the color base coating film as a single film is adjusted to a specified range.

Method for forming excellent multi-layer coating film

A method of forming a multi-layer paint film comprising coating an aqueous first colored base paint (A) on an electro-deposition paint cured paint film to form a first colored base paint film, coating an aqueous second colored base paint (B) on the first colored base paint film without preliminary heating of the first colored base paint film to form a second colored base paint film, coating a clear paint (C) coated on the second colored base paint film after preliminary heating of the first paint film and second paint film to form a clear paint film, and heating and curing the three paint films at the same time, wherein a talc pigment is included in each of paint (A) and paint (B) in an amount of from 1 to 5 mass % with respect to the total resin solid fraction of each of paint (A) and paint (B).

Method for the formation of multi-layer paint films

A double-structure coated object includes an outer plate portion configured to produce a target color by stacking a coating film of a first paint and a coating film of a second paint, and an inner plate portion on which a coating film of the second paint is formed. When the coating film is formed on the inner plate portion, and then the first paint and the second paint are sequentially applied to the outer plate portion, paint dust on the inner plate portion is prevented from causing viewers to feel something different about color. To achieve this, the ratio (1BC)/(1BC+2BC) of the spectral reflectance (1BC) of the color of the coating film made of the first paint to the spectral reflectance (1BC+2BC) of the target color is configured to fall within a predetermined range.

A decorative film structure includes: a surface layer constituted by a transparent or translucent resin layer; an achromatic layer constituted by dots provided on a back surface of the surface layer; and a metal luster layer provided on the back surface of the surface layer to fill a gap between the dots. As surface roughness of a front surface of the surface layer, an Ra is 2 &#x3bc;m or less and either an Rmax is 4 &#x3bc;m or less or a Sm is 50 &#x3bc;m or more. A lightness L* of the achromatic layer is 0-80. An area of each dot when viewed from a front side of the surface layer is 10-10&#x3bc;m. A dot area percentage per a unit area when viewed from the front side of the surface layer is 1-80%. A stimulus value Y45&#xb0; of the metal luster layer is 10000 or more.
